NUMBERlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No.49'7,'729, dated May 16,1893.

Application filed December 12, 1892. Serial No. 454,837 (No model.)

T at Lu/tom it may concern:

Be it known that I, FRANK SANDERS, a subjeot of the Emperor of Germany,and a resident of Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements inNumbering-Machines; and I do hereby declare that the following is a fulland exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, making a partof this specification.

I-Ieretofore printers numbering-machines have been formed as singlemachines which may be locked in the form with the type and actuated bythe pressure of the platen. They have also been arranged to be fixed atdifferent points within a frame and to be actuated by a rod or barmovable in a plane parallel with the bed-plate of the press, or by someother device specially applied to the press for the purpose. The singlemachines are well adapted for most uses butfor some other purposes theyare not so well adapted both because they must be locked in a form andbecause the actuating mechanism therefor must be placed within the frameof the numbering-head itself. Machines of the other class referred toare free from the objections just noted but so far as known to me theycannot always be placed exactly in the most desirable position onaccount of the necessity for fixed guides for the horizontally movablerods or other devices referred to and furthermore in order to give theproper movement to the said rods or devices it is necessary to add someother mechanical devices to the press.

It is therefore the object of my invention to overcome the severalobjections noted and to provide a numbering machine in which thenumbering-head itself may be shifted to any desired posit ion, even tothe fraction of an inch, and in which one or more heads may be fixed asdesired, while the wheels are advanced by the direct pressure of theplaten upon a vertically moving plunger which stands at the margin ofthe bed-plate.

In the accompanying drawings: Figure l is a plan view of a numberingmachine embodying my improvement, portions of the frame being brokenout. Fig. 2 is a side elevation of the same with a portion of thecovering plate at the right broken away. Fig. 3 is a section on the linea2a2 of Fig. 1. Fig. 4 is a detail view of a portion of the actuatingbar with the sliding finger in position. Fig. 5 is a detail view of oneend of the machine, showing a slightly diiferent arrangement.

The numbering-head itself may be of any preferred construction and asshown in Figs. 1, 2 and 3, comprises a casing a, numberwheels I), I),mounted on a fixed shaft 0, spring holding pawls d, (1, and a swingingframe e which carries the driving pawls f, f. The numbering-head issupported by a frame which may be of any desired length and whichconsists of a bar 9 rigidly fixed to two end blocks h, h. lhe bar 9 isformed with a longitudinal slot i. Thumb-screws 7c, 70, pass through theslot into the casing a and serve to secure the numbering-head in anydesired position. Each end block h has a vertically movable,spring-seated plunger m which engages, as by a pin on and slot 0, thecorresponding end of a vertically-formed actuating barp. Guide-ways forthe ends of the bar may be formed by recessing each block and securing acovering plate q over the recess. The bar 10 is slotted or preferablyformed with a dove-tail groove 1" to receive the end of a sliding plateor finger s which moves with the numbering-head as the latter isadjusted along the bar g, a guide-way for the finger being formed by aplate 25 fixed to the casing a. The finger sis provided with a pin towhich passes through a slot in the casing a and engages the swingingframe.

The operation of my improved numbering machine will be understoodreadily. As the plungers m, m, are depressed by the pressure of theplaten and rise as the platen moves away the actuating bar 12 is alsodepressed and rises and through the finger s imparts the necessarymovement to the swinging-frame.

I have shown a single numbering-head secured to the bar 9 but it isevident that as many as desired might be secured to the same bar andoperated in the same manner as the single head.

I claim as my invention- The combination of a frame composed of a barwith end-blocks rigidly fixed thereto, a numbering-head and means forsecuring the same to the bar in any desired position,vertically-rnovable spring-seated plungers supported by said end-blocks,an actuating-bar connected to said plunger-s, and a sliding-finger inengagement with said actuating-bar and transmitting its movements to themechanism 0f the numbering-head, substantially as shown and described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

FRANK SANDERS.
